It is the midpoint of the class interval. I.e let b=the highest number in the class, a = the lowest number in the class. The midpoint is (a+ 1/2(b-a)).

### What is class boundary in statistics?

class boundary is the midpoint between the upper class limit of a class and the lower limit class of the next class sequence when making a class interval starting at the lowest lower limit in the bottom of a table.

### How do you find class midpoint?

It is the middle of the class. e.g. 0&lt;l&lt;10 - class midpoint is 5 because it is the middle of the class. e.g. 25&lt;t&lt;50 - class midpoint is 37.5 because it is the middle of the class Midpoint = MIDDLE

### What is class width?

Class width, from statistics, is the difference between the two boundaries of a class. A class is an interval that includes all of the values in a (quantitative) data set that fall within two numbers, the lower and upper limits of the class. Finally, a class boundary is the midpoint of the upper limit of one class and the lower limit of the next class.

### What is a 'crude mode'?

Crude Mode (Grouped data) is the midpoint of the class limit with the highest frequency. Therefore, in getting the Crude Mode, look for the highest frequency and look at it's class limit. Lastly, get he class limit's midpoint. The Class Limit's midpoint will be the Crude Mode (Grouped Data).

### Example of a class size in statistics?

### Does the midpoint of a frequency distribution class equal the sum of the lower and upper limits?

No, the midpoint is the result of adding the upper and lower limits in a class and dividing that by 2. Essentially the mid point is the average of the two limits.
